   Yes I considered custom crystals, but I'm holding out of one domestic source   
   that someone in the "groups" knows of...   
      
   If we're talking history, when designed were published in electronics   
   magazines inevitably the crystal that drove them were 9.54545 (NTSC standard)   
   here in USA and Japan, et. al., or 8.86723 (PAL standard) in Europe, et. al.   
   These 2 crystals were ubiquitous.   
      
   Now I cant steal one.   
      
   Thanks.
